LDAP lookups fail

Try one or more of the following:

Make sure that the server and firewall settings are configured to allow communication between the printer and the LDAP server on port 389 or port 636

If you are using SSL, then use port 636. Otherwise, use port 389.

Make sure that the LDAP server address contains the host name, not the IP address

For more information, see Configuring LDAP network account settings.

If the LDAP server requires SSL, then make sure that the SSL settings are correct

For more information, see Configuring LDAP network account settings.

Narrow the LDAP search base to the lowest possible scope that includes all necessary users

Make sure that all LDAP attributes are correct
